I'm trying to create a scene (animation) where a figure walks through a small fog bank (or cloud of smoke). I want them to be completely obscured for a moment before reemerging from the fog. Any ideas on how to accomplish this? I only have Poser ProPack, Rhino, and the Max4 demo I got from 3DWorld a couple of months ago and haven't installed yet. (I'm saving my 15 days until I really need it.)
